风景旅游公园环境噪声预测

Prediction on Enviromental Noise in Tour Parks.

对杭州市主要风景旅游公园进行为时两年的环境噪声监测、调查与分析。用回归分析方法得出公园环境噪声预测公式,发现景点游客密度每增加2.7倍,景点环境噪声等效声级增加3dB。以此公式用于类比公园,取得较为理想的预测效果。

A survey and investigation was made on the environmental noise at main parks in Hangzhou,it has been found that the noise level will increase by 3. 2 dB when the density of tourists at scenery sites raised to 2. 7 times. Regression equations are given in this paper. Using the equations to predict the noise level in other parks,the results are agree with the actual data well.
